portion of females to males). Other abnormalities not connected with 

 hermaphroditism are discussed. It is shown that the P. capitis may 

 acquire all the characters of P. corporis; the two are but races of 

 P. humanus. J. A. T. 



Abor Collembola. — G. H. Carpenter {Records Indian Museumy 

 1917, 8, 561-8, 3 pis.). A new genus, Cyp^hoder apsis, is established for 

 G. keyyipi sp. n., a blind, pale, scaled spring- tail, found by Stanley W. 

 Kemp under stones at Rotung, North-East Assam, at an elevation of 

 1400 feet. The spring has a rigid tapering dens, with a double row 

 of strong spines and a delicate distal scale-appendage. The mucro is 

 elongate and narrow, with terminal and dorsal teeth. This remarkable

genus resembles Cyphoderns in many respects, and may be regarded as 

 a connecting link between typical Cyphoderini and the Paronellini. Its 

 features are so striking that Carpenter has no hesitation in establishing 

 the ne,v genus and species on a single specimen. New species of 

 Protanura, Lepidocyrtus^ and Paronella are described. J. A. T.

Occurrence of Craterostigmus tasmanianus in New Zealand. — 

 Gilbert Archey {Trans. New Zealand Inst., 1916, 49, 319-20). This 

 unique genus of centipedes, the sole representative of the order Cratero- 

 stigmophora, occupies according to Pocock an intermediate position 

 between Scolopendromorpha and Lithobiomorpha. It has hitherto been 

 known only from two specimens collected on the summit of Mount 

 Rumney, Tasmania. It has now been found abundantly within a certain 

 range in New Zealand. " The occurrence of such an archaic form as 

 Craterostiymus in both New Zealand and Tasmania is of considerable 

 interest, for it may be regarded as having some significance in connexion 

 with the question of a former land connexion between these two 

 countries." J.A. T.
